Defining relative displacement on ABAQUS (as opposed to absolute displacement)

[SwimBikeRun4342]

I have a body on ABAQUS that translates and rotates a bit. I want to create an object that is NOT connected to the main body but displaces relative to that body. Is there any way to apply a relative displacement in ABAQUS, as opposed to the conventional absolute displacement boundary condition?

I would really like to be able to simply define the relative displacement of this object relative to the main body.


I'm open to any suggestions
Thanks!

I have not tried this so these are a couple shots in the dark:

1. Can you attach a coordinate system to a node on your reference and apply the displacement using that coordinate system? What I am not sure about is whether the coord sys will move with a particular node or if it will stay fixed.

2. I am sure you could do this with a user defined subroutine (probably DISP). But that would surely be painful.

HTH,
